Mikel Oyarzabal was not supposed to be captain. According to the protocol established by Luis de la Fuente, the same one he had used in the lower categories of Spain, the leaders of the dressing room would be established not by age but by games with the national team. And so it was that Morata, Rodri, Carvajal and Dani Olmo took the lead in the group. However, De la Fuente had an extra concept when choosing his captains: his own will. If the coach saw a player with the ability to lead, he would add him to the group of leaders. The one chosen by the coach was Mikel Oyarzabal, precisely the player who gave Spain its fourth European title. It was not the only case, the coach not only bet, but also fought, so that certain players had their place and their weight, both on the field and in the dressing room. Some of them, even when everything seemed to indicate that the coach was wrong. De la Fuente was right, they were too: the coach looked after them; Laporte, Cucurella, Fabián, Morata, Nico Williams and Lamine Yamal have all made a name for themselves.
